SHOVEL ATTAGHNIENT FOR DISK CULTIVATOR S.

Specification of Letters Patent. Patented Aug. 11, 190. Applicationfiled December 9, 1907. -Serial No. 405,669.

To all whom it may concern:

Be it knownthat l, JONATHAN L. Bornn, a citizen of the United States,residing at Elvaston, county of Hancock, and State of Illinois, haveinvented certain new and use Shovel Attachments ful Im rovements in forDis Cultivators, of which the following is a specification.

My invention relates to disk cultivators and particularly to attachmentsfor disk cultivators.

The object of my invention is to provide shovel attachment for diskcultivators which will adapt the cultivator for working close to youngcorn or other small plants without disturbing them or tearing thegrowing roots.

Other objects will appear hereinafter.

.My invention consists generally in a shovel attachment for diskcultivators adapted to re )lace the inner disk of each gang.

[y invention further consists in means for adjusting the shovel asdesired.

My invention further consists in various details of construction andarrangements of parts all as will be hereinafter fully described andparticularly pointed out in the claims.

My invention will be more readily understood by reference to theaccompanying drawings forming a part of this specification and in which,

Figure 1 is a front elevation of a ortion of a. disk cultivator equippedwith t 1e shovel attaclu'uents embodying my invention in its preferredform, Fig. 2 1s a )ers ective view of one of the gangs equippet wit ithe shovel attachment, and Fig. 3 is a detail section.

Referring to the drawings, 1 indicates the usual arch or cross bar of adisk cultivator, upon each side of which is mounted the usual gang. 2.Each gang of a disk cultivator usually comprises three disks and it isthe obiject of my invention to replace the inner t isk of each gang by ashovel attachment. In working young corn or other small plants, with anordinary disk cultivator, the ground cannot be worked sulliciently closeto the plants without disturbing them or tearing the tender growingroots. By replacing the inner disks with a shovel, the ground may beworked close to the young plants without detriment.

In carrying out my invention, I remove the inner disk of each gang andsubstitute a longer bolt, 3 for the one upon which the disks are mountedand upon the end of the The shovel attachment comprises a sleeve mountedon the bolt, 3 and adapted to rotate therewith, a non-rotary sleevemounted thereon and having a flange or lug formed upon one side thereof,a clevis secured to the flange or lug and having a bifurcated end towhich the shank of the shovel is adjustably secured and a suitable clamparranged upon the arch. or cross member of the frame to receive the endof the shank.

4 indicates the rotary sleeve mounted u on the bolt. This is providedwith a head, 5 which bears against thebox 6 of the gang, or against theend of the bearing spool, 7.

U )011 the sleeve 4 is mounted a second or rounds the opposite end ofthe sleeve and 13 a nut forsecurmg the parts together. The sleeve, 4 isslightly longer than the sleeve, 8 so that when the nut, 13 binds the ca'1'1 firmly against the end of the sleeve, 4, tie sleeve 4 is free torotate within the sleeve, 8. The flanges, 10 and 12 prevent dust andgrit from entering the bearings. Formed upon the sleeve, 8 is a lug'orllange, 14 by means of which the shovel attaching clevis is securedthereto.

15 indicates the clcvis. This is provided with a pair of arms, 16 whichreceive the sleeve bet-ween them. A bolt, 17 assing through suitableholes in the end of t 10 arm, 16 and the lug, 14 secures the clcvis tothe sleeve. The lug, 14 is arranged upon the rear of the sleeve, 5 andthe clcvis extends forwardly therefrom terminating at its forward end ina pair of lugs, 18 forming a vertically disposed groove, 19 betweenthem, to receive the shank of the shovel.

20 indicates the shovel secured to the lower end' of the shank, 21. Theshank, 21 comprises a flat-plate adapted to enter the groove, 19 and isprovided with a plurality of holes, 22 to receive a bolt, 23 extendingthrough the lugs, 18. It is obvious that the shank is readily adjustablein the clcvis to raise or lower the shovel as desired. The shank of theshovel terminates at its upper end in a stem, 24. This is )refcrably cyindrical and is arranged to Slit e vertically in a 27 indicates a setscrew in the sleeve adapted to impinge against the stem, 24

llOlt ing the shovel firmly in osition.

The device herein descriied is of simple construction, of low cost tomanufacture and may be readily and uickly attached to the cultivator. Toattac 1 the device the inner disk is removed and the long bolt, 3substituted for the usual one. The sleeves bearing the clevis are thenslipped in place together with the cap, 11 and secured in position bythe nut, 13. The stem of the shovel shank is then slipped into thesleeve, 25 and the shank secured to the clcvis. proper position, thebolt, or set screw, 27 is tightened.

Having described my invention what I claim as new and desire to secureby Letters Patent is:

After the shovel is in 3. In a disk cultivator, a frame and a gangcomprlsing a spindle bolt and a plurality of disks, in combination witha sleeve mounted upon the spindle bolt, a clevis secured to said sleeve,a shovel secured to said clevis and means on said frame for bracing saidshovel, substantially as described.

4. In a disk cultivator, a frame and a gang comprising a spindle boltand a plurality of disks, in combination with a-sleevc mounted upon thes )indle bolt, a clevis secured to said sleeve, a s iovel having a shankadiustably secured to said clevis and means on said frame for engagingsaid shank to brace the shovel, substantially as described.

5. In a disk cultivator a frame and a gang comprising a spindle bolt anda plurality of disks in combination with a sleeve mounted JONATHAN L5,;
